Sanjay Kumar Pal, Sumeet Anand · SSRN Electronic Journal · 2018
Nowadays, the world runs on information. Information is nothing but solutions or answers to different types of queries. It is composed of well-defined data and operations. The information has led to the rise of knowledge and this knowledge has great potential to make or destroy nations. There are practically two sets of information—general purpose information such as this is year 2018 and sensitive information such as the nuclear codes of a country. There is no need to protect the general purpose information, but just imagine that one nation gets hold of the nuclear launch codes of another country; it can wreak havocs. With the development and advancement in the field of technology, there is a need to protect vulnerable information. This is where the Information Security or InfoSec answers the call. These are a set of methods used to protect valuable information as most of them reside over the interconnected systems of computer networks. It has a lot of positive aspects such as mobility and portability,, but also since everything is connected, there are ways to access other systems and steal or alter the information. This is called hacking and people involved in these works are termed as hackers. Thus, to protect the information, various methods have been proposed, and this paper studies some of the methods and their working principles.
